Doesn't make sense for a belt to squeal only when shifting, are you sure it is a belt? Is the belt old or dryed out and cracked looking?
Try using a bar of soap and while the engine is running at an idle, CAREFULLY, hold the bar of soap up against the belt to "coat" it. If it is a belt, this should stop the squeal temporarily. If it does, then replace the belt. If it doesn't, then it isn't your belt.

It's a common problem, believe it or not. What's happening is that the belt slips a tiny bit due to the shock from the RPMs dropping so drastically when shifting at high rpms, then loading back up again. Mine did it when I bought it also, and my '99 did it as well. Mine was more of a chirp than a squeal though.

I replaced the belt with a Gatorback, and it hasn't done it since.

Are you sure it is in the engine bay? Have you had a listen to the throw out bearing lately? It would make sense for a throw out bearing to squeal when shifting as that is when it contacts the clutch fingers and starts spinning. Can you duplicate the squeal at any time other than high rpm shifting?

Hey, iv'e got the same issue, 98 GT though. Do not use any type of lubricant or soap or anything on your belt. Big mistake, just causes more issues. I have not yet got around to fixing mine yet, but i would reccomend: Take off your current belt, Spin each pulley, take a high grit piece of sand paper, and scuff the pulleys that ride on the back side of your belt. You could lightly touch your belt with a little more coarse piece of sand paper, but id just say upgrade to a better quality belt. Hope it works out for you.
